- Description:
- Hydrogels have been used for decades in various applications such as drug delivery, water absorption, biomedical scaffolds, and separations processes. This project is to investigate hydrogels as possible agents for absorption of metal and organic compounds in water. We have investigated different chelating agents and synthesis methods to best achieve this goal. Leaching studies of different compounds like dichlorobenzene (DCB) from the hydrogel have been investigated. When the hydrogel was exposed to different metal ions, it showed that it could be used as a colorimetric indicator of metals in the solution down to the 74-ppm level. Part of this work also showed that different metal nanoparticles can be added into the hydrogels like titanium oxide and iron oxide. During the characterization of pore size using SEM it was shown that nanocrystals were formed on the surface of the polymer. This observation showed that 3 nm metal organic nanosheets can be created at room temperature and within 24 hrs. It also shows that there is some interaction between the nanosheets and the polymer. Future work should explore how this can be achieved.
